HAWKER®’s modular charging revolution continues with the new LIFESPEED® MOD3 charger - the latest innovation of high-frequency switch-mode smart chargers from HAWKER®, the world leader in high-frequency charging technology. Offering the flexibility of a fast charger, an opportunity charger, and a straight-through charger, LIFESPEED® MOD3 chargers provide optimum charging, peak efficiency, and non-stop power while reducing charging costs and energy demands.

Benefits and Highlights
Combining HAWKER®’s LIFESPEED® charging expertise with the advantages of modular technology, LIFESPEED® MOD3 chargers deliver a variety of benefits to enhance your operation.

  • Fast Charging – The LIFESPEED® MOD3 charger utilizes patented AccelRate® technology to create a unique charge algorithm. When combined with the exceptional efficiency and power factor of high-frequency switch mode technology, these chargers can recharge your batteries 3-5 times faster than conventional units.
  • Energy Savings – LIFESPEED® MOD3 technology offers the highest conversion efficiency and power factor available in the industry – significantly reducing electrical consumption and demand charges. The LIFESPEED® MOD3 operates at efficiencies of up to 94% and a power factor of .96.
  • Plug-and-Play Flexibility – The LIFESPEED® MOD3 responds dynamically to charge a wide range of battery voltages and capacities without user intervention. LIFESPEED® is the easiest high-frequency switch-mode charger in the industry to operate. On-site programming capabilities allow the charger to be custom tailored to the application’s specific needs.
  • Advanced Data Management – The chargers communicate wirelessly with the Battery Boss® WC (BBWC) and maintain a data history of numerous charge parameters for analysis and optimization. Optional Ethernet interface can provide network connectivity for remote monitoring and data collection with HAWKER®'s LifeNetwork™.
  • Opportunity Charging – The LIFESPEED® MOD3 includes a distinct opportunity charge profile which returns capacity to the battery during breaks without excessively gassing the battery. The opportunity profile can be set either manually using front panel menus or automatically using  HAWKER®’s BBWC.


Every module in the HAWKER® LIFESPEED® MOD3 chargers are stand-alone, eliminating the risk of catastrophic failures and downtime.




Coupled with the BBWC, this patented charge algorithm enables the LIFESPEED® MOD3 charger to automatically adapt to battery voltage, AH capacity, and state of charge. This provides a 100% amphere hour return from an 80% DoD in just 2-3 hours while avoiding excessive heat generation.
Through a patented charge algorithm, the AccelRate® profile reduces the natural resistance of the battery by inserting discharge cycles at precise intervals into the charging profile. This homogenizes the ion field around the plates, promoting a far better distribution of the active ions over the entire charging area. Therefore, a substantially higher charging current can be applied and maintained, resulting in a much faster charge with a controlled increase in the electrolyte temperature.

The LIFESPEED® MOD3 offers two additional charge profile options based on your operation’s requirements:

  • IONIC – This patented, exclusive profile is the preferred choice for most applications. Employing periodic current pulses which both identify the battery’s true capacity and state of charge, as well as mix the electrolyte throughout charge to avoid acid stratification. This profile provides the optimal recharge with minimal heating.
  • Opportunity – The charger current is up to a 25% start rate depending on battery and charger size.

The opportunity profile may be used with or without a BBWC. When employing a BBWC, the charger will change profiles based on the BBWC’s settings. Without a BBWC, you must program the charger in opportunity charge mode.

Equalize and complete charge time parameters must be programmed through the charger configuration screen.

  • Cold Storage Program – The LIFESPEED® MOD3 charger series automatically engages to the cold storage program if the battery temperature is below 59°F.


  • Power You Can Count On – The new high-frequency modular LIFESPEED® MOD3 charger supplies dependable, proven power – delivering maximum reliability and improved efficiency to keep you moving.
  • Simplified Service – The LIFESPEED® MOD3 self- diagnostics feature alerts operators to any possible failures. Replacement modules are available for quick delivery, and because of their design, installation is fast and simple.
  • Flexible. Adaptable. Fast. – The modules in HAWKER®’s chargers automatically adjust to effectively charge the battery while maintaining optimal efficiency and best power factor.

The modular design of the LIFESPEED® MOD3 allows for adaptation to a variety of battery capacities, potentially reducing or eliminating the need for more chargers in your fleet.

  • Eliminate Downtime – When employing two to twelve* individual power modules, LIFESPEED® MOD3 chargers provide you with a non-stop charge. Even if one module stops working, the rest will keep working to continue  charging the battery – making downtime a thing of the past.
  • Scalability for Future Needs – Our modular charger design offers the advantage of scalability. The 6-bay and 12-bay* LIFESPEED® MOD3 charger cabinets allow modules to be added in response to changing power needs. Your current operations may require only a few modules to effectively charge your batteries, but if your workload changes, these larger cabinets can quickly accommodate additional modules to meet your expanded power requirements.
  • Environmentally Engineered – The HAWKER® LIFESPEED® MOD3 chargers consume less electricity, simultaneously reducing battery recharge costs while positively impacting our carbon footprint.

The modules in the HAWKER® LIFESPEED® MOD3 chargers work as a team to deliver consistent power. Even if one module goes down, the other modules will continue charging.
